Decadal hindcast simulations of Arctic Ocean sea ice thickness made by a modern dynamic - thermodynamic sea ice model and forced independently by both the ERA - 40 and NCEP / NCAR reanalysis data sets are compared for the first time.
for longer term
decadal hindcasts a linear trend correction may be required if the model does not reproduce long - term trends.

doi: 10.1007 / s00382 -012-1313-4 who report quite limited predictive skill in two regions of the oceans on the
decadal time period, but no regional skill elsewhere, when they conclude that «A 4 - model 12 - member ensemble of 10 - yr
hindcasts has been analysed for skill in SST, 2m temperature and precipitation.
I think we should conclude that we agree on the fact that on shorter (
decadal) time scales GCM / RCM have shown little regional skill to predict /
hindcast observed changes.

Hindcasting the Pacific
Decadal Oscillation in relevance to a near - term climate prediction.
We find a close agreement between the CESM - based
hindcasts and the Markov model, indicating that the largest contribution to the predictive skill of soil water on interannual to
decadal timescales in CESM can be attributed to the damped persistence, which is partly governed by the evapotranspiration (Delworth and Manabe 1988), the total runoff, and the diffusion of soil moisture into the deeper soil levels as shown in the Eq.
This
hindcast setting roughly follows the experimental design of the Coupled Model Intercomparison Project - 5 (CMIP5) for
decadal climate prediction (Taylor et al. 2009; Murphy et al. 2010).
There is active modelling to
hindcast and forecast yields of major crops with data from
decadal time spans under climate change.
